Commonly found in Central and South America, the bot fly is notorious for its unsettling reproductive method. The female bot fly lays eggs on a host animal, and the larvae burrow under the skin to feed, often causing painful lesions.

Known for delivering one of the most painful stings in the insect world, the bullet ant is found in the rainforests of Central and South America. The pain from its sting is often compared to being shot—hence its name.

These large insects, found in waters across the Americas, can grow up to 4 inches long. They are powerful predators, with a bite that can deliver a painful toxin to both insects and fish.

A wasp with a frightening method of reproduction, the tarantula hawk paralyzes tarantulas with its sting, then lays an egg on the spider. The hatched larva will eat the still-living tarantula from the inside out.

Also known as “killer bees,” these insects are highly aggressive. Their venom is not more dangerous than regular honeybees, but they attack in large numbers, which can be deadly.
